Description

[Detailed Description of the Invention] The present invention relates to an improvement of the sliding plate attachment part in a current collector.

A sliding plate is generally attached to the part of the current collector that comes into contact with the contact wire.

This sliding plate wears out as it is used for a long time and must be replaced, but as the frequency of use increases, the frequency of replacement also increases.

A conventional sliding plate mounting portion of this type is, for example, as shown in FIG. 5, in which a sliding plate 2' is screwed and fixed to a current collector head body plate 1' with bolts 13'.

Therefore, in the past, it was necessary to tap the sliding plate, which was time-consuming; and to replace the sliding plate, each bolt had to be removed one by one and screwed in again, which was time-consuming. There are drawbacks such as.

The present invention eliminates these drawbacks and provides a sliding plate mounting portion of this type that allows easy replacement of the sliding plate and requires less machining of the sliding plate.

That is, the sliding plate mounting portion of the current collector of the present invention has a collector head main body plate 1 and a sliding plate 2 placed thereon, and sliding plates are provided at both front and rear ends and left and right ends of the main body plate 1, respectively. Fixed locking pieces 11, 12, 13, 14 protruding from the side where the plate is placed are provided, and one of the locking pieces 13 at both left and right ends further has a slope H for holding down the sliding plate 2, and Among the locking pieces at both ends, one end of the main body plate on the side of the locking piece 14 that does not have the slope on the other side is rotatable so as to press the sliding plate 2 onto the main body plate 1 by spring force with the end direction as the axial direction. A presser plate 3 is provided, and the presser plate 3
The sliding plate 2 is sandwiched between the body plate 1 and the body plate 1 by spring force so that the holding plate 3 can be fixed, and the plate is placed on the body plate 1 using the above-mentioned fixed locking pieces 11, 12, 13, 14. Stop the sliding plate 2 from moving forward, backward, left or right, and press the sliding plate 2 with the slope H of the holding plate 3 and the fixed locking piece 13 facing it, and place the sliding plate on the current collector head main body plate. It is characterized in that it is fixed to.

The present invention will be further explained with reference to FIGS. 1 to 4 illustrated below.

In Fig. 1, 1 is the current collector head main body plate, 11.12 is the fixed locking piece at the front and rear ends of the main body plate 1, and 13.14 is the main body plate 1.
, H is the slope of the locking piece 13, 2 is the sliding plate placed on the main body plate 1, and 3 is the end direction of the locking piece 14 of the main body plate 1 in the axial direction. 31.32 are both legs of the holding plate 3, 4 is a shaft, and 15.16 is a shaft mounting portion attached to the main body plate 1. shown respectively.

As mentioned above, the head body plate 1 has a fixed locking piece 11°12.1
3.14 is attached, and the sliding plate 2 can be attached to the head main body plate 1 by a presser plate 3 on which a spring force acts.

That is, the holding plate 3 has a mechanism that can rotate around the shaft 4.

The shaft 4 is attached to the head body plate 1 so as to be rotatable and movable in the front and back directions (arrow in the figure), and is supported by a coil spring 5.
It is a mechanism that interlocks with the presser plate 3 via.

Screws 6 and 7 hold the ends of the coil spring 5 on the holding plate 3, respectively.
This is for fixing to the shaft 4.

A pin 8 is attached to the shaft 4, and the pin 8 is fitted into a groove 91 of a hollow cylinder 9 fixed to the head body plate 1.

Since the pin 8 of the shaft 4 is guided by the guide groove 91, the shaft 4 cannot freely rotate or move in the longitudinal direction.

Now, FIG. 2 shows a schematic view from the side when the pin 8 is in the part B in FIG. 1.

At this time, the pressing plate 3 is not pressing the sliding plate 2, and the sliding plate 2 is in a detachable state.

Next, when the pin 8 comes to the part A in FIG. 1, the presser plate 3 should be in the state shown in FIG. 3 unless the spring 5 is twisted.

However, as shown in Figure 4, since there is a sliding plate 2, the presser plate 3
The rotation angle is smaller than in the case of FIG. 3, and the sliding plate 2 is held down.

At this time, the spring 5 is twisted, and the holding plate 3 is pressed against the sliding plate 2 by the twisting force.

That is, when attaching the sliding plate 2, the shaft 4 is twisted to change the pin 8 from position B to position A as shown in FIG.

The shaft 4 is fixed (locked) in the state A by the action of the guide groove 91, pin 8, and spring 5.

At this time, the sliding plate 2 is firmly fixed to the current collector head body 1.

Next, when removing the sliding plate 2, the pin 8 is released from being locked in the position A by rotating and pushing the shaft 4 as shown in FIG. 1, and returned to the position B.

When the pin 8 comes to position B, the sliding plate 2 can be attached and detached freely.

According to the present invention as described above, ■ The sliding plate can be replaced in a one-touch manner using spring force.

That is, it is extremely easy to replace the sliding plate. @No need to tap the sliding plate.

In other words, less machining of the sliding plate is required.

It has the following advantages.
